Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a multi-carrier or multi-cell transmission scheme and apparatus in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet these diverse performance demands, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) plenary meeting #72 decided to conduct research on New Radio (NR) (or 5G). The 3GPP RAN plenary meeting #75 approved the WI (Work Item) for New Radio, initiating standardization work on NR.

[0003] Multi-carrier technology (including carrier aggregation and dual connectivity) is a key component of the new air interface (NR). To adapt to diverse application scenarios and meet different requirements, 3GPP has been evolving multi-carrier technology since Rel-15. Summary of the Invention

[0004] Cross-carrier scheduling is supported in multi-carrier communication processes, such as carrier aggregation (CA). In networks supported by existing standards, such as 5G New Radio (NR) versions R17 and earlier, scheduling of multiple scheduled carriers is only supported on the corresponding carriers or corresponding PDCCHs (Physical Downlink Control Channels), and scheduling through the same PDCCH on the same carrier is not supported.

[0005] The present application discloses a solution to the problem of simultaneously scheduling multiple carriers or multiple cells with the same PDCCH in a NR multi-carrier system. It should be noted that in the description of this application, PDCCH scheduling in multi-carrier is used as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (such as other scenarios with higher requirements for control channel capacity, including but not limited to capacity enhancement systems, systems using higher frequencies, coverage enhancement systems, power saving modes, unlicensed frequency domain communications, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) networks, vehicle networks, etc.), and can also achieve similar technical effects. In addition, the use of a unified solution for different scenarios (including but not limited to multi-carrier scenarios) also helps reduce hardware complexity and cost. In the absence of conflict, the embodiments and features of the embodiments in the first node device of this application can be applied to the second node device, and vice versa. In particular, the interpretation of terminology, nouns, functions, and variables in this application (unless otherwise specified) can refer to the definitions in the 3GPP 5GNR specification protocol.

The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and supports handover of the first node device between the second node devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node device and the first node device. The radio protocol architecture of the user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second node devices in the user plane 350 is substantially identical to the corresponding layers and sublayers in the control plane 300, including the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355. However, the PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also includes the SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping QoS flows to data radio bearers (DRBs) to support service diversity.Although not shown, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., an IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.).

[0268] In the DL (Downlink), upper layer packets, such as the high-layer information included in the M1 information blocks in this application, are provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. In the DL, the controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and allocation of radio resources to the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first node device 450. For example, the high-layer information included in the M1 information blocks in this application is generated in the controller / processor 440. The transmit processor 415 performs various signal processing functions for the L1 layer (i.e., the physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation. For example, the physical layer signal for the M1 information block, the physical layer signal corresponding to the first DCI, and the physical layer signal corresponding to the second DCI in this application are generated by the transmit processor 415. The generated modulated symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. The symbols are then mapped by the transmit processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of RF signals. At the receiving end, each receiver 456 receives the RF signal via its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to the receive processor 452. The receive processor 452 performs various signal reception processing functions for the L1 layer. The signal reception and processing function includes receiving the physical layer signals of the M1 information blocks in this application, the physical layer signals of the first DCI, and the physical layer signals of the second DCI, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK)), and then descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node device 410 on the physical channel, and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and the controller / processor 490 interprets the high-level information included in the M1 information blocks in this application.
